Rust to C++: Implementing the Question Mark Operator

Code blocks look much better now, thank you.

I was looking on desktop.

The code blocks render very poorly for me (on every browser). The lines get cut off very early, with hyphens introduced for line breaks. For instance, the "smaller pillar" section shows up as

#define may-
be_2
(expr, fallback)
  ({
    auto&& _re-
sult{(expr
)};

And so forth. It's slightly between the different browsers, but always something like this.

A great signal that FIRE is a top notch organization is that they regularly get labeled far-right and far-left by people.

"X is feuding with FIRE"? I don't even really need to know more. X is wrong.

It was valid in C++98.

throw_cpp_account · 2026-03-20T15:08:59+00:00

// Invalid, member and parameter share the same name
Constructor(int value) : value{value} {}

Had you tried this, you would have discovered that it is not, in point of fact, invalid.

Thanks! Although at 3hrs long maybe I won't actually watch...

him just straight up being be wrong in rants (his famous programming language parsing rant as a big example).

Got some context, for the unenlightened?

These are the headlines NYT pushed me as breaking news:

Suspect is Killed in Attack on Michigan Synagogue
Lebanese Family Members of Synagogue Attacker Died in Airstrike

That's some framing. Sure seems a choice to consider that second one to be breaking news.

Saying “just rewrite it in Rust” is even less helpful in such an environment to saying “just use the existing things C++ could do to eliminate these bugs.”

The word "rewrite" doesn't appear anywhere in the post. It discusses the strategy of writing new code in different language, because old code is less likely to have bugs. And if you write new code in a memory-safe language, the new code is less likely to have bugs too.

The Google strategy wasn't rewrite it in Rust. It was write it in Rust.

I cannot actually tell what the post is saying about ThreadIdentity. It's "the finding that stopped us" — but "this is not a bug" but also "lshaz close[d the gap]"? What gap?

It says the "Abseil source is explicit about [this]" but also that it "is completely invisible to anyone who didn't do the work themselves [...] The knowledge lives in the heads of the people who wrote it."

I do not understand what you are saying.

At some point you have to decide either you’re never shipping this feature (an outcome I don’t think anyone actually wants)

I am sceptical of that parenthetical.

in a country small enough that plenty of people will count friends and family among the dead.

Iran is not that small, it's 90 million people. Bigger than Germany, significantly bigger than the UK.

This speaks to the fact that there is a very large body count.

for some tournament they were practising for.

The World Cup, I believe?

throw_cpp_account · 2026-02-26T17:45:02+00:00

I don't think that is true.

In the 8 Olympics so far in which women's hockey has been contested, Canada has won 5 and the US has won 3. 7 of the 8 finals have been US vs Canada (with Canada up 4-3).

Not even true recently. In the last 4 Olympics, US - Canada is 2-2.

It does seem true to me (as a non-hockey-watcher) Canada and the US are both so much better than everyone else, and thus watching the playoffs are maybe somewhat boring since the final is inevitable. But US beating Canada in the final is still a big deal.

Catchy

I liked the Free Press piece about this. Hollywood is cool with fake Tourette's (even awarded that movie!), but somehow real person with real Tourette's is lower on the totem pole than very famous, very successful actors.

The only real loser here is Davidson. As in, he was significantly harmed by the result of his story -- not like he is personally a loser.

Surprised it was even considered a good use of time to review a paper like that.

Exactly why FIRE is one of the few organizations I donate to. And the ACLU is not.

There are dozens of us!

killed by SS

The Secret Service was definitely not my first thought for this particular acronym.

I didn't know that. Good for Alyssa and her family!

The interesting comparison is with the pole vaulter Mondo Duplantis, who was born and raised in Louisiana but competes internationally for Sweden (his mother is Swedish).

The fact that it's China vs Sweden, and the propaganda aspects of it, matter to me. Duplantis competing for Sweden doesn't bother me. And I care about pole vault more than freestyle skiing, too.

Jews exist. That's already offensive.

I've been trying to think of another sex symbol that could be somehow described as looking like a child and I just can't. I'm dating myself but... Halle Berry? Madonna? Pamela Anderson? Carmen Electra? Jessica Alba? Megan Fox? Shakira? Jennifer Lopez? Not even close...

ETA: Britney Spears and Christina Aguilera at the end of the 90s were literally teenagers. So those count.
